The Dell XPS 13 9360 uses a QCA Rome chip which needs to be reset
(and have its firmware reloaded) for bluetooth to work after
suspend/resume.

Jeremy Cline correctly points out in rhbz#1514836 that a device where the
QCA rome chipset needs the USB_QUIRK_RESET_RESUME quirk, may also ship
with a different wifi/bt chipset in some configurations.
If that is the case then we are needlessly penalizing those other chipsets
with a reset-resume quirk, typically causing 0.4W extra power use because
this disables runtime-pm.
This commit moves the DMI table check to a btusb_check_needs_reset_resume()
helper (so that we can easily also call it for other chipsets) and calls
this new helper only for QCA_ROME chipsets for now.

Commit f44cb4b19ed4 ("Bluetooth: btusb: Fix quirk for Atheros
1525/QCA6174") is causing bluetooth to no longer work for several
people, see: https://bugzilla.redhat.com/show_bug.cgi?id=1568911
So lets revert it for now and try to find another solution for
devices which need the modified quirk.

With patch 279c936153199 the btuart_cs driver has been deprecated in
favor of serial_cs + hci_uart combination.
static struct pcmcia_device_id btuart_ids[] = {
/* don't use this driver. Use serial_cs + hci_uart instead */
PCMCIA_DEVICE_NULL
};
Intead of keeping it around, just remove it since it is not even
assigned to any PCMCIA identifiers anymore.

When adding the alignment and padding support for H:4 packet processing

The HCILL or eHCILL protocol from TI is actually an H:4 protocol with a
few extra events and thus can also use the h4_recv_buf helper. Instead
of open coding the same funtionality add the extra events to the packet
description table and use h4_recv_buf.

Now that we need just an ACPI HID in the table, and the driver auto-
configures itself otherwise, we can easily add a bunch of known ACPI HIDs.
This avoids having to add these 1 by 1 as devices with one are encountered
by users.
This commit may seem as if it simply adds all IDs between BCM2E00-BCM2EAC,
but that is not true, all these IDs were found in actual .inf files and
the range is not entirely continuous, the following IDs are not added:
BCM2E6A, BCM2E6C, BCM2E8F and BCM2E91 because I did not see these in any
.inf files. As for the large amount of IDs this seems to be caused by
Broadcom using a separate ID for every bluetooth module using their
chips. E.g. BCM2EA6 seems to be specifically for the Raspberry Pi 3.

Since I've been doing a lot of work on Linux Bay Trail / Cherry Trail
support, I've gathered a collection of ACPI DSDTs from about 50 such
machines.
Looking at these DSTDs many have an ACPI device entry describing a bcm
bluetooth device (often disabled in the DSDT), quite a few of these ACPI
device entries have a resource-table where the order does not match with
the order currently associated with the HID of that entry in the
bcm_acpi_match table.
Looking at the Windows .inf files, there is nothing indicating a specific
order there, so I believe that there is no 1:1 mapping between the ACPI
HID and the order in which the resources are listed.
Therefor this commit replaces the hardcoded mapping based on ACPI HID,
with code which actually checks in which order the resources are listed
and bases the gpio-mapping on that.
This should ensure that we always pick the right mapping and this will
make adding new ACPI HIDs to the driver easier.
This has been tested on the following devices:
-Asus T100CHI BCM2E39 / brcmfmac43241b4-sdio / BCM4324B3-37.4M.hcd
-Asus T100TA BCM2E39 / brcmfmac43241b4-sdio / BCM4324B3-37.4M.hcd
-Asus T200TA BCM2E65 / brcmfmac43340-sdio / BCM43341B0-37.4M.hcd
-Jumper ezPad mini 3 BCM2E74 / brcmfmac43430a0-sdio / BCM4343A0-26M.hcd
-Acer Iconia Tab8 w1-8 BCM2E83 / brcmfmac4330-sdio / BCM4330B1-26M.hcd
-Chuwi Vi8 plus(CWI519) BCM2EAA / brcmfmac43430-sdio / BCM43430A1-26M.hcd
Which together cover all 3 combinations of using an Interrupt resource /
GpioInt resource as first resource / GpioInt resource as last resource.

We declare the same set of const acpi_gpio_params twice with different
names, besides the needless duplication this naming leads to a sortof
double indirection which also makes it harder to see how the mapping is
actually setup.
This commit renames the first set to have generic names, which better
describe the contents of the mapping and drops the second set.

Older devices with a serdev attached bcm bt hci, use an Interrupt ACPI
resource to describe the IRQ (rather then a GpioInt resource).
These device seem to all claim the IRQ is active-high and seem to all need
a DMI quirk to treat it as active-low. Instead simply always assume that
Interrupt resource specified IRQs are always active-low.
This fixes the bt device not being able to wake the host from runtime-
suspend on the: Asus T100TAM, Asus T200TA, Lenovo Yoga2 and the Toshiba
Encore, without the need to add 4 new DMI quirks for these models.
This also allows us to remove 2 DMI quirks for the Asus T100TA and Asus
T100CHI series. Likely the 2 remaining quirks can also be removed but I
could not find a DSDT of these devices to verify this.

Some GPIO controller drivers request sleepable context and so can't
be accessed from IRQ context. Using gpiod_set/get_value accessors
with such controller leads to a kernel warning since they are
reserved for atomic context (according to the documentation).
Use the postfixed _cansleep version instead, indicating that context
is safe for sleeping if necessary. Note that this is the case here
since we never toggle the gpio neither from IRQ nor from a spinlocked
section.

The linkage between the bluetooth driver and the wireless
driver is not defined properly, leading to build problems
such as:
warning: (BT_HCIRSI) selects RSI_COEX which has unmet direct dependencies (NETDEVICES && WLAN && WLAN_VENDOR_RSI && BT_HCIRSI && RSI_91X)
drivers/net/wireless/rsi/rsi_91x_main.o: In function `rsi_read_pkt':
(.text+0x205): undefined reference to `rsi_bt_ops'
As the dependency is actually the reverse (RSI_91X uses
the BT_RSI driver, not the other way round), this changes
the dependency to match, and enables the bluetooth driver
from the RSI_COEX symbol.

include/net/rsi_91x.h.
Major changes:
wl1251
* read the MAC address from the NVS file
rtlwifi
* enable mac80211 fast-tx support
mt76
* add capability to select tx/rx antennas
mt7601
* let mac80211 validate rx CCMP Packet Number (PN)

Fun set of conflict resolutions here...
For the mac80211 stuff, these were fortunately just parallel
adds. Trivially resolved.
In drivers/net/phy/phy.c we had a bug fix in 'net' that moved the
function phy_disable_interrupts() earlier in the file, whilst in
'net-next' the phy_error() call from this function was removed.
In net/ipv4/xfrm4_policy.c, David Ahern's changes to remove the
'rt_table_id' member of rtable collided with a bug fix in 'net' that
added a new struct member "rt_mtu_locked" which needs to be copied
over here.
The mlxsw driver conflict consisted of net-next separating
the span code and definitions into separate files, whilst
a 'net' bug fix made some changes to that moved code.
The mlx5 infiniband conflict resolution was quite non-trivial,
the RDMA tree's merge commit was used as a guide here, and
here are their notes:
====================
Due to bug fixes found by the syzkaller bot and taken into the for-rc
branch after development for the 4.17 merge window had already started
being taken into the for-next branch, there were fairly non-trivial
merge issues that would need to be resolved between the for-rc branch
and the for-next branch. This merge resolves those conflicts and
provides a unified base upon which ongoing development for 4.17 can
be based.
Conflicts:
drivers/infiniband/hw/mlx5/main.c - Commit 42cea83f9524
(IB/mlx5: Fix cleanup order on unload) added to for-rc and
commit b5ca15ad7e61 (IB/mlx5: Add proper representors support)
add as part of the devel cycle both needed to modify the
init/de-init functions used by mlx5. To support the new
representors, the new functions added by the cleanup patch
needed to be made non-static, and the init/de-init list
added by the representors patch needed to be modified to
match the init/de-init list changes made by the cleanup
patch.
Updates:
drivers/infiniband/hw/mlx5/mlx5_ib.h - Update function
prototypes added by representors patch to reflect new function
names as changed by cleanup patch
drivers/infiniband/hw/mlx5/ib_rep.c - Update init/de-init
stage list to match new order from cleanup patch

The IRQ output of the bcm bt-device is really a level IRQ signal, which
signals a logical high as long as the device's buffer contains data. Since
the draining in the buffer is done in the tty driver, we cannot (easily)
wait in a threaded interrupt handler for the draining, after which the
IRQ should go low again.
So instead we treat the IRQ as an edge interrupt. This opens the window
for a theoretical race where we wakeup, read some data and then autosuspend
*before* the IRQ has gone (logical) low, followed by the device just at
that moment receiving more data, causing the IRQ to stay high and we never
see an edge.
Since we call pm_runtime_mark_last_busy() on every received byte, there
should be plenty time for the IRQ to go (logical) low before we ever
suspend, so this should never happen, but after commit 43fff7683468
("Bluetooth: hci_bcm: Streamline runtime PM code"), which has been reverted
since, this was actually happening causing the device to get stuck in
runtime suspend.
The bcm bt-device actually has a workaround for this, if we set the
pulsed_host_wake flag in the sleep parameters, then the device monitors
if the host is draining the buffer and if not then after a timeout the
device will pulse the IRQ line, causing us to see an edge, fixing the
stuck in suspend condition.
This commit sets the pulsed_host_wake flag to fix the (mostly theoretical)
race caused by us treating the IRQ as an edge IRQ.

This reverts commit 43fff7683468 ("Bluetooth: hci_bcm: Streamline runtime
PM code"). The commit msg for this commit states "No functional change
intended.", but replacing:
pm_runtime_get();
pm_runtime_mark_last_busy();
pm_runtime_put_autosuspend();
with:
pm_request_resume();
Does result in a functional change, pm_request_resume() only calls
pm_runtime_mark_last_busy() if the device was suspended before the call.
This results in the following happening:
1) Device is runtime suspended
2) Device drives host_wake IRQ logically high as it starts receiving data
3) bcm_host_wake() gets called, causes the device to runtime-resume,
current time gets marked as last_busy time
4) After 5 seconds the autosuspend timer expires and the dev autosuspends
as no one has been calling pm_runtime_mark_last_busy(), the device was
resumed during those 5 seconds, so all the pm_request_resume() calls
while receiving data and/or bcm_host_wake() calls were nops
5) If 4) happens while the device has (just received) data in its buffer to
be read by the host the IRQ line is *already* / still logically high
when we autosuspend and since we use an edge triggered IRQ, the IRQ
will never trigger, causing the device to get stuck in suspend
Therefor this commit has to be reverted, so that we avoid the device
getting stuck in suspend.

The issue can be reproduced before commit fd865802c66b ("Bluetooth:
btusb: fix QCA Rome suspend/resume") gets introduced, so the reset
resume quirk is still needed for this system.

Commit 1fdb92697469 ("Bluetooth: btusb: Use DMI matching for QCA
reset_resume quirking"), added the Lenovo Yoga 920 to the
btusb_needs_reset_resume_table.
Testing has shown that this is a false positive and the problems where
caused by issues with the initial fix: commit fd865802c66b ("Bluetooth:
btusb: fix QCA Rome suspend/resume"), which has already been reverted.
So the QCA Rome BT in the Yoga 920 does not need a reset-resume quirk at
all and this commit removes it from the btusb_needs_reset_resume_table.
Note that after this commit the btusb_needs_reset_resume_table is now
empty. It is kept around on purpose, since this whole series of commits
started for a reason and there are actually broken platforms around,
which need to be added to it.

According to the devicetree binding the shutdown and device wake
GPIOs are optional. Since commit 3e81a4ca51a1 ("Bluetooth: hci_bcm:
Mandate presence of shutdown and device wake GPIO") this driver
won't probe anymore on Raspberry Pi 3 and Zero W (no device wake GPIO
connected). So fix this regression by reverting this commit partially.

Commit 61f5acea8737 ("Bluetooth: btusb: Restore QCA Rome suspend/resume fix
with a "rewritten" version") applied the USB_QUIRK_RESET_RESUME to all QCA
USB Bluetooth modules. But it turns out that the resume problems are not
caused by the QCA Rome chipset, on most platforms it resumes fine. The
resume problems are actually a platform problem (likely the platform
cutting all power when suspended).
The USB_QUIRK_RESET_RESUME quirk also disables runtime suspend, so by
matching on usb-ids, we're causing all boards with these chips to use extra
power, to fix resume problems which only happen on some boards.
This commit fixes this by applying the quirk based on DMI matching instead
of on usb-ids, so that we match the platform and not the chipset.
Here is the /sys/kernel/debug/usb/devices for the Bluetooth module:

This is the mindless scripted replacement of kernel use of POLL*
variables as described by Al, done by this script:
for V in IN OUT PRI ERR RDNORM RDBAND WRNORM WRBAND HUP RDHUP NVAL MSG; do
L=`git grep -l -w POLL$V | grep -v '^t' | grep -v /um/ | grep -v '^sa' | grep -v '/poll.h$'|grep -v '^D'`
for f in $L; do sed -i "-es/^\([^\"]*\)\(\<POLL$V\>\)/\\1E\\2/" $f; done
done
with de-mangling cleanups yet to come.
NOTE! On almost all architectures, the EPOLL* constants have the same
values as the POLL* constants do. But they keyword here is "almost".
For various bad reasons they aren't the same, and epoll() doesn't
actually work quite correctly in some cases due to this on Sparc et al.
The next patch from Al will sort out the final differences, and we
should be all done.

The Bluetooth parts of RTL8723D and RTL8723B share the same lmp
subversion, thus we need to check both lmp subversion and hci revision
to distinguish the two. The same situation is true for RTL8821A and
RTL8821C. Accordingly, the selection code is revised.
To improve maintainability, a new id_table struct is defined, and an
array of such structs is constructed. Adding a new device can thus be
as simple as adding another value to the table.

download_firmware() is never called from atomic context.
It is only called by ll_setup() that is called only via function pointer
"->setup" used in hci_uart_setup() in drivers/bluetooth/hci_serdev.c and
drivers/bluetooth/hci_ldisc.c. hci_uart_setup() is called only
via function pointer "->setup" used in hci_dev_do_open()
in net/bluetooth/hci_core.c.
All of the above functions do not enter atomic context.
Besides, ll_setup() calls msleep() and hci_dev_do_open calls mutex_lock().
So it indicates that all the above functions call functions that can sleep.
Despite never getting called from atomic context, download_firmware()
calls mdelay() for busy wait.
That is not necessary and can be replaced with msleep to avoid busy wait.
This is found by a static analysis tool named DCNS written by myself.

btmrvl_send_sync_cmd
After checking all possible call chains to btmrvl_send_sync_cmd(),
my tool finds that this function is never called in atomic context,
namely never in an interrupt handler or holding a spinlock.
And it calls wait_event_interruptible_timeout() after bt_skb_alloc(),
so it indicates that btmrvl_send_sync_cmd()
can call function which can sleep.
Thus GFP_ATOMIC is not necessary, and it can be replaced with GFP_KERNEL.
